Connected TV media planning: audience, budget, frequency and measurement

What does CTV mean in advertising?

CTV means connected TV: television content viewed on a smart TV or through an internet-connected device such as a streaming stick, set-top box or games console. CTV advertising is the video inventory served within that experience. It can be bought directly from a broadcaster or streaming service, through a programmatic guaranteed deal, in a private marketplace or through an open auction.

The device matters because a television screen is normally shared, watched at distance and used in a high-attention video setting. Targeting and measurement, however, still depend on the publisher, device, consent signals, household graph and buying route. A CTV impression should therefore be treated as a delivered ad opportunity on a connected television, not automatically as one verified person reached.

Decide what CTV should do in the media plan

CTV earns investment when its role is clearer than 'we need television'. Start with the campaign objective and the audience behaviour, then state the job in one sentence. For example: reach streaming-first households with a product demonstration before paid search captures active demand. That role gives the planner a basis for comparing CTV with linear TV, YouTube, social video and other reach channels.

Choose the CTV buying path

The buying path determines how much certainty, transparency and flexibility the plan receives. It should be recorded on each media plan line, together with the named supply source and the fees included in the budget. 'Programmatic CTV' alone is not a complete buying instruction.

A mixed route can be sensible: reserve must-have publisher inventory, use PMPs for named environments and keep a controlled open-auction line for reach. Separate those routes in the plan so a low-cost open-auction impression cannot conceal under-delivery from a premium deal.

Build the audience from the available signals

CTV targeting often operates at household or device level. Depending on the provider, a plan may use first-party customer matches, demographic or interest segments, viewing context, content genres, geography, retargeting or broad reach. Document what the segment actually represents, who supplied it, whether consent and permitted use are clear, and which device or household identifiers support activation.

Do not copy a strategic persona directly into a buying platform and assume precision. Translate the persona into observable signals, record where those signals are weak, then compare the resulting addressable audience with the reach requirement. The workflow in audience personas for media planning helps separate the audience idea from the platform proxy used to buy it.

• Define the strategic audience and the specific addressable proxy used in each publisher or DSP.
• Estimate eligible households or devices after geography, consent, inventory and match-rate constraints.
• Apply customer, converter, employee and other relevant exclusions consistently where the technology permits.
• Record whether reporting represents devices, households, accounts or modelled people.
• Keep a broad or contextual alternative when a narrowly matched audience cannot support the required reach.

Set a CTV budget from reach, cost and role

There is no universal percentage of a media budget that should go to CTV. Size it from the role: the audience you need to reach, the frequency needed for the message, the CPM and fees available through the chosen supply, the campaign length, creative capacity and the minimum investment required for valid measurement. Then compare that case with the next-best use of the money.

A worked CTV budget example

Assume an illustrative £240,000 video budget for a six-week launch. The planner gives CTV the job of adding large-screen reach among streaming households, YouTube the job of scalable online-video reach, and social video the job of rapid creative learning. A first scenario allocates £100,000 to CTV, £80,000 to YouTube and £60,000 to social video. These figures are planning assumptions, not customer data or recommended benchmarks.

If the working all-in CTV CPM is £25, £100,000 implies four million impressions: budget divided by CPM, multiplied by 1,000. At an assumed average frequency of four, the simple mathematical ceiling is one million reached devices or households. It is only a scenario check. Uneven frequency, ineligible inventory, duplicated devices, fees and differences between household and person counts can all reduce comparable reach. The planner should replace assumptions with supplier forecasts and show a range, not convert the division into a promise.

Stress-test at least a low, central and high CPM or reach case. If the CTV line loses its purpose as cost rises or available reach falls, set that threshold in advance. The wider allocation method is covered in how to allocate a media budget across channels.

Plan frequency across fragmented supply

A cap inside one publisher or DSP does not automatically cap the same household across every streaming service, device and buying platform. Plan a combined frequency intention, then assign practical limits by supply line. Consolidating buying where it improves identity and control can help, but no dashboard should be assumed to provide perfect cross-platform de-duplication.

1. Set a campaign-level frequency range appropriate to the message, audience size and flight length.
2. Map every CTV, YouTube, social-video and linear-TV line likely to reach the same audience.
3. Choose publisher or DSP caps that leave room for exposure elsewhere rather than each line using the full campaign limit.
4. Inspect the distribution where available: the average can look acceptable while a smaller group receives excessive exposure.
5. Create a decision rule for rising frequency, such as widening supply, refreshing creative or moving budget to an under-reached audience.

Prepare creative for the television screen

CTV creative should work at viewing distance, in a shared room and within the technical requirements of each supply source. Use legible text, strong visual hierarchy, clear brand attribution and an ending that can be understood without a click. Confirm accepted duration, aspect ratio, file weight, audio, captions, tracking and review lead time before the production deadline.

Interactive formats and QR codes can create a bridge to a phone, but they add operational and measurement requirements. The IAB Tech Lab CTV Programmatic Guide describes standards for delivery, targeting, measurement, interactivity, transparency and brand suitability. Ask the provider which formats and signals are supported in the actual inventory being bought rather than assuming every CTV environment behaves the same way.

Use a four-layer CTV measurement plan

Measurement should answer four different questions: did the ads deliver, was the delivery acceptable, who was reached, and did the campaign change an outcome? A video completion rate can inform the first two questions, but it cannot establish incremental reach or business impact by itself.

CTV measurement signals remain uneven across devices and platforms. The IAB Standardized Measurement Guide for CTV highlights how fragmented standards and inconsistent signal quality complicate impression, viewability, reach, frequency and attention measurement. Name the counting method and source beside every KPI, and avoid adding incompatible reach estimates as if they were de-duplicated people.

For outcomes, match the method to the decision. Platform-attributed conversions can support optimisation within a platform; a controlled brand-lift study can estimate a surveyed change; geo or audience experiments can test incrementality; and marketing mix modelling can examine broader contribution over time. Define the comparison, window, sample and success threshold before launch. How to measure brand lift covers the exposed-versus-control design in detail.

Questions to ask a CTV provider

CTV supply can pass through several sellers and technical systems. The planner needs enough transparency to know what is being bought, how it is counted and what controls are actually available. The IAB Tech Lab and World Federation of Advertisers publish a current buyer question guide for CTV providers, including questions about measurement standards, forecasting and accurate signalling of live content.

• Which publishers, apps, programmes, devices and geographies can be reported, and at what level?
• Is the seller direct or an intermediary, and how is the authorised supply path verified?
• How are impressions, completion, viewability, reach and frequency defined and independently verified?
• Does frequency control work across the provider's whole supply or only within individual publishers or devices?
• How are co-viewing and the difference between devices, households and people handled?
• Which audience identifiers and data sources are used, and what match rate and privacy controls apply?
• Which content, app, fraud and brand-suitability controls are available before bidding and in reporting?
• Which fees are included in the quoted CPM, and which sit outside it?
• What happens when a direct deal or PMP under-delivers?
• Which data can be exported for independent cross-channel analysis?

Operate CTV as part of one media plan

The approved plan should preserve the CTV role after activation. Give each buying route its own line, use one naming taxonomy, record whether costs are gross or net, and monitor actual spend against a weighted planned-to-date baseline. Under-delivery may reflect an unrealistic forecast, a deal floor, restricted targeting, creative approval or supply availability; diagnose the cause before opening targeting or moving money.

Medusa can hold CTV beside search, social and other channels in the cross-channel allocation, with its role, budget, flighting, KPI and rationale visible in the approved plan. Where actual delivery data is connected or imported, planners can compare planned and actual spend and evaluate reallocation in the context of the whole campaign. Availability and reporting depth still depend on the buying platform and data supplied, so provider-level measurement should remain explicit.
